2018 Toronto municipal election (47-ward model)

The 2018 Toronto municipal election operated in two distinct phases. Phase 1 (47-ward model) was approved on appeal by the Ontario Municipal Board and was in effect from the beginning of the election through to August 14, 2018.

The province of Ontario ordered a change midway through the election cycle initiating a second phase (25-ward model) which ran from August through to election day. Phase 1 candidacy and campaign finance remain a matter of official public record, however it is the results of phase 2 that decided the final composition of the 2018 -2022 Toronto City Council.

Councillor and school trustee races which relied on ward boundaries as a condition were substantially affected. Mayoral races which covered the city as a whole were administrated differently in terms of polling methods, but were otherwise less affected.
